meso-to-meso 2,5-Pyrrolylene bridged zig-zag porphyrin arrays have been synthesized via a stepwise Suzuki-Miyaura cross coupling reaction. Both the dimeric and trimeric structures of Zn porphyrin were confirmed by X-ray diffraction analysis. DFT calculations indicate that the porphyrin oligomers are all in zig-zag conformations. The UV/Vis absorption and emission spectra of these porphyrin oligomers were red-shifted as the number of their porphyrin units increased.
通过逐步的铃木-宫浦交叉偶联反应合成了中对中2,5-吡咯撑桥连之字形卟啉阵列。锌卟啉的二聚体和三聚体结构均通过X射线衍射分析得到证实。密度泛函理论计算表明，卟啉低聚物均呈之字形构象。随着卟啉单元数量的增加，这些卟啉低聚物的紫外/可见吸收光谱和发射光谱发生红移。
